Great Savings & Free Delivery / Collection on many items.� Buying a sailboat is a significant investment, and fortunately, you can find inexpensive used sailing boats for sale on eBay to fit your budget. Different types of sailboats. When you are searching for sailing boats for sale in the UK to fit your lifestyle, you should know what kinds there are. These are the main types of sailing boats for sale UK area-wide: Beach catamaran - Catamarans have two parallel hulls that are equally sized. They are stabilised from possessing a wide beam, rather than from a keel with ballast like a mono-hull sailing boat. �Code Sail� is a general term for a specialized class of fast, flat and furling-capable downwind sails that are defined by mid-girth measurements between 50%% of foot length. These sails fit between upwind headsails and downwind spinnakers. Code Sails are especially effective on high-performance monohulls and multihulls. The Code Zero model meets the minimum 75% smg requirement to be classified as a Spinnaker for certain rating rules. Customized sail shapes are combined with a luff loaded sail structure to provide unparalleled speed and stability. 3Di Code Sails feature highly specialized f.

On my footer I carry a 1. Downwind sails differ from conventional headsails in two respects. First, headsails have a fairly flat shape similar to an airplane wing while downwind sails have fuller shapes optimized for greater apparent-wind angles. Second, downwind sails gain additional sail area with positive luff and leech curves�the area outside the triangle formed by the head, tack, and clew. The greater the luff and leech curves, the larger the sail will be.

Sail Area For a given mast height, a symmetric spinnaker will contain more sail area than either of the other two types. An asymmetric spinnaker will have roughly 15 to 25 percent less area than a symmetric spinnaker, and a Code 0 gennaker with the same luff length will have about 30 to 40 percent less.

Table 2 shows the approximate areas of the sails I use on my foot cruising boat. Because both luffs of the sail are the same length, the shape of the sail on either side of the centerline is the same�hence symmetric. There is a large amount of positive curve to the luff areas on a symmetric spinnaker, and the sail can be carried effectively with the apparent wind as far forward as 65 to 75 degrees.

Symmetric spinnakers require a spinnaker pole to fly correctly. The pole is the reason that the symmetric is the only one of the three types that can remain stable when sailing at apparent-wind angles larger than degrees. The symmetric spinnaker requires the most lines and rigging and takes the most effort to set, gybe, and douse.

This is a disadvantage of the sail, but when you want to sail downwind at deep up to degrees apparent-wind angles, the symmetric is the best sail for the job. Asymmetric spinnakers are built with a different shape on each side of the centerline, so the sail has a defined luff and leech with the luff longer than the leech.

The maximum width of an asymmetric is usually slightly smaller than that of a symmetric, the area at the head of the sail has a flatter shape, and the total area is smaller. The figure below illustrates the difference in sail area between an asymmetric spinnaker, a Code 0, and a conventional genoa. An asymmetric will start to be ineffective once the apparent wind moves farther aft than about degrees, although setting it in a wing-and-wing configuration with a whisker pole will extend its effectiveness at greater angles.

Gybing an asymmetric involves easing the sheet and allowing the clew of the sail go forward and around in front of the headstay.

In most cases the best way to do this is with a second, or lazy, sheet that is attached to the clew of the sail and led forward around the headstay and back aft to a winch. During a gybe the luff and tack attachments of an asymmetric do not change. The sail basically turns inside out in front of the headstay. A Code 0 is effectively a cross between a genoa and a spinnaker.

Code 0 sails, although they are fuller than a genoa, are much flatter in cross-section than either a symmetric or asymmetric spinnaker. The luff curve of a Code 0 is slightly positive, but not as great as the asymmetric.

The leech also has a positive curve, but again less than an asymmetric. In 5-toknot winds a Code 0 sail can be effective in apparent-wind angles as far forward as 35 to 45 degrees and as far aft as to degrees. A Code 0 sail is gybed the same way as an asymmetric. The sail has a rope or light wire on the luff that allows it to be roller-furled. To douse the sail, you ease the sheet, pull on the furling line, and the Code 0 rolls back around the luff and can then be lowered to the deck.

Code 0 sails should be set on a bowsprit or retractable extension, such as a sprit or prod. This moves its furling drum forward and clear of both the genoa roller-furling drum Boat Sailing Lights Zip Code and the bow pulpit. Sail selection To pick the right off-wind sail or sails, you need to consider four criteria. Ease of handling In general, the smaller the crew and the lower the experience level, the easier the sail must be to handle. A Code 0 sail, with its roller-furling capability, is the easiest to set and drop.

If conditions require it, a rolled Code 0 can remain hoisted until conditions allow it to be lowered safely. And, of course, it is also easy to gybe. The symmetric spinnaker is the most difficult to handle because of its large size, pole, and extra rigging. Although a snuffer removes some of the control problems when lowering the sail, it still requires the most skill and manpower. Cost The cost includes more than the sail itself.

It comprises the spinnaker pole and fittings, spinnaker sock, sheets, control lines, and perhaps a furling system. In terms of total cost, a symmetric chute is the most expensive, a Code 0 the second most expensive, and an asymmetric the least costly.

Performance If you are making long offshore passages and expect to do a lot of downwind sailing, a good inventory of downwind sails can take days off your passage time. If you are planning shorter passages, the extra speed you get from multiple downwind sails will be less relevant, and having just one downwind sail may be sufficient.

If you plan to carry only one off-wind sail, an asymmetric will be the most flexible. Storage Sails and their associated gear obviously take up space, so this is an important consideration. A Code 0 sail requires the least stowage space when furled , followed by the asymmetric and the symmetric.

Design Downwind sails can be made to reflect the target wind angle you want to sail. Smaller apparent-wind angles require a flatter shape; higher apparent-wind angles require a fuller shape for best performance. Construction Symmetric and asymmetric off-wind cruising sails are often made of nylon fabrics in.

Polyester fabric, such as Dacron, is often used for Code 0 sails in weights that can range from 1. Mylar, polyester, and exotic fibers like Spectra and Vectran can be used in high-tech laminates for downwind sails.

But unless you want a racing sail, my recommendation is to stick with a nylon fabric. For a cruising boat over 35 feet, or for any boat that sails shorthanded, 1. In light air a 1. Nylon is more susceptible to UV degradation than polyester.

I respectfully disagree. The design of the sail and the equipment that controls them are exceptional. Add a couple of downwind sails to your inventory and spice up your cruising life. To make handling it easier, use a spinnaker sock.
